Hello all,
If you do not have the patience (like me) to collect, clean and test many many many used laptop cells or having a hard time to find them (also like me), using new cells is a fast(er) way to build a powerwall.
Instant powerwallmay be a bit of aoverstatement, it is still very muchtime consuming to build thepacks and the inclosure, but forsurefaster then collecting and testing used cells,so respect for all those who put in the time and effort toinspire and guideother builders.
After somedoubt, i like to share my build.
Love to get your remarks to do things better and safer.
it is all up and running now, next step will be adding a " fast charger " with 3 Elcon flatpack2 chargers, controlled by the bms and powerdwith my generator with heat recovery, for the darker winter day's, not sure it will work but love to do some tests.
Also like to distribute the DCbattery powerfor all of the LED lights true the house (with some 12v converters.)
Some of thespecs:
Cells: Panasonic ncr18650pf, 2900mAh
battery setup: 2 strings 14s90p,all the cells are in parralel so more of a 14s180p setup, with space to expand (with used laptop cells? )
inverter: infinisolar (mpp) 48v 10kw 3phase.
bms: batrium.
solar: 18x300Wp
Greatings,
